Late-night laughs

"President Barack Obama addressed the U.N. General Assembly. His opening line was, 'Some of you may recognize me from my appearances on television.'" — Jay Leno

"The president has been on so many shows lately, even Ryan Seacrest was like, 'Dude, slow down.'" — Jimmy Kimmel

"You know the former governor of Alaska, Sarah Palin? Boy, I know her. She's traveling all over the world now, speaking gigs. And she went to Hong Kong and gave a speech, and people who heard the speech said it was articulate, it was well-prepared, it was compelling. It's a year late, but. . . . And if it was that good, I'm thinking it must have been Tina Fey." — David Letterman
